Strain flxr musc/fasc/tend l little fngr at forarm lv, subs

This code signifies a non-traumatic overstretching or tearing of the flexor muscles, fascia, or tendons specifically affecting the little finger on the left hand, with the injury located at the forearm level. This injury typically results in pain, swelling, and limited movement of the affected finger.

This code is used for follow-up encounters for patients receiving active treatment for a strain of the flexor structures of the left little finger at the forearm. It is appropriate for subsequent visits after the initial diagnosis and treatment has begun, but the patient is not yet fully recovered.

• Ensure the documentation specifies the left little finger and the injury location at the forearm level.
• Verify that the encounter is for a subsequent visit, not the initial injury or sequela.
• Confirm the injury is a strain, not a sprain, rupture, or other type of trauma.
